What this means is a weekend mini-season of movies featuring swimming pools and swimming all projected on to a giant 'air-screen' in the garden beside the Lido.

The films on show include the cult 1968 classic The Swimmer, starring Burt Lancaster and the ultra-camp 1952 biopic Million Dollar Mermaid about legendary Australian swimmer Annette Kellerman, which features a Busby Berkeley synchronised swimming spectacular and a boxing kangaroo.

As a finale there's a whole day of surprise 'swimming shorts' courtesy of global film label Future Shorts who will be transforming the Lido into a 20s-style leisure complex complete with dance routines and ushers in swimming costumes.

And if boxing kangaroos and ushers in trunks weren't enough to entice you the ticket price also includes a swim in the fantastic 100 yard pool, and a celebratory Centenary drink. Bottoms up!

If you can't wait til the end of July, you could also check out London's 'first outdoor film festival', this weekend in Greenwich Park.
